Abstract

The relation between functional antihemophilic factor (AHF) activity and AHF-like antigen was studied in the plasma of 25 known carriers of hemophilia. In 23 cases, this relationship was significantly different from that in normal women, at the 99% limit of confidence. In contrast, among families in which only one case of hemophilia had occurred, only five of nine mothers could be identified as carriers. This observation suggests that in some instances the hemophilia arose from a newly mutant gene. The data are consistent with the hypothesis that the proportion of antigen to AHF activity in carriers is determined by random activation or inactivation of the X chromosome.

摘要

对25名已知血友病携带者的血浆中功能性抗血友病因子(AHF)活性与AHF样抗原之间的关系进行了研究。在23例中,这种关系在99%的置信限下与正常女性有显著差异。相比之下,在仅出现一例血友病的家庭中,9名母亲中只有5名可被确定为携带者。这一观察结果表明,在某些情况下,血友病源于新的突变基因。这些数据与以下假设一致,即携带者中抗原与AHF活性的比例由X染色体的随机激活或失活决定。
